CRS Version

"How can I verify what version CRS is?".

The version of CRS can be higher than the version of database/ASM software. The commands to see the same are

crsctl query crs softwareversion
crsctl query crs activeversion

So although the difference between the two commands might be obvious I am not sure if this is documented anywhere. Also after upgrading from to the active version does not seem to change. This maybe due to bug 5278777 which should be fixed in the patchset.

I upgraded a couple of clusters yesterday from to (without any issues per se) and this is what I see after the CRS upgrade.

elephant-> crsctl query crs softwareversion
CRS software version on node [elephant] is []
elephant-> crsctl query crs activeversion
CRS active version on the cluster is []

elephant-> cemutlo -w

The cemutlo command is used by the EM agent to query CRS version.

Also a rolling upgrade of CRS causes the VIP to relocate to some other node and you have to manually relocate the same using crs_relocate. This is mentioned in the patchset readme though I am not sure how many customers actually read the section “Known Issues”.
